LH Wiper Seal – Heavy-Duty Metal-Cased Hydraulic Excluder for Large-Bore Cylinders and Extreme Contamination.
LH heavy-duty wiper seal with metal casing for extreme contamination. Aggressive scraping, rigid retention, severe-duty durable. PU/NBR + steel, –40°C~110°C.
LH Wiper Seal – A rugged heavy-duty hydraulic wiper seal engineered for extreme contamination control in large-bore cylinders and off-highway equipment. This metal-cased excluder features an aggressive scraper lip that effectively removes heavy mud, ice, clay, and abrasive debris from the rod surface during retraction. The optional secondary lip retains lubrication film and provides light fluid sealing for added protection. The rigid metal casing provides structural reinforcement, prevents extrusion and deformation, and ensures secure groove retention under severe shock loads, vibration, and temperature extremes. The wear-resistant polyurethane or NBR wiping element delivers excellent resistance to weathering, ozone, UV, and abrasive media. This severe-duty excluder seal is ideal for large-bore hydraulic cylinders, mining equipment, construction machinery, agricultural implements, and off-highway vehicles exposed to the harshest operating conditions. Material: wear-resistant polyurethane/NBR wiping element with galvanized or stainless steel casing. Temp: –40°C to +110°C.
